TED einen@ MARSHALL B. LLOYD, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TOLLOYD MANU- FACTURING COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION.

COLLAPSIBLE Gro-CART.

To all whom it may concern:

Be it known that I, MARSHALL B. LLOYD, of Minneapolis, Hennepin county,Minnesota, havev invented certain new and useful Improvements inCollapsible `Gro-Carts, of which t-he following is a specification.

My invention relates to a childs collapsible go-cart, and the object ofthe invention is to provide a frame for the cart of substantial, durableconstruction though comparatively light and easily handled, and onet-hat is capable of being easily and quickly collapsed or extended asdesired.

A further object is to provide improved means for locking the frame inits extended or expanded position and positively preventing itspremature collapse.

A further object is to provide a collapsible frame for a go-cart that iscapable of being folded into a very compact form for convenience inshipping or storing the same.

The invention consists generally in various construct-ions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figurel is a vertical sectional view of a go-cart embodying my invention, inits expanded position. F ig. Q is a similar view showing the frame ofthe cart partially collapsed. Fig. 3 is a sectional view showing theframe entirely collapsed. Figs. 4, 5 and 6 are detail views illustratingthe operation of expanding and locking the frame in its expandedposition.

In the drawing, 2 and 3 represent the forward and rear carrying wheelsof the cart mounted upon axles 4 and 5. 6 is a frame mounted at its rearend on the axle 5 and curved upwardly and forwardly therefrom andprovided at its forward end with a cross bar or rod 7. This frame I willhereinafter refer to as the wheeled frame or the cart frame todistinguish it from the frame on which the seat is mounted. Bars 8 arepivoted on said rod and extend downwardly beyond the same to the forwardaxle 4 and the said bars project upwardly above the frame 6 and arepivotally connected at their upper ends to bars 9 which form. the backof the frame of the cart. The bars 8 and 9 form that part of the cartwhich I prefer to designate as the seat frame, to distinguish it fromthe arched frame having the carrying wheels. A cross Specification ofLetters Patent.

rod l0 is carried by the frame 6 and guiding straps 1l have their endssecured on each side of the cart to the bars 9 and form therewith anarrow guide 12 through which the cross rod l0 extends, and on which thebar 9 slides during the operation of folding or extending the frame. Thelower ends of the bars 9 are provided with notches' 13 to receive therod l0 and plates 14 4are pivoted at 15 on the said bars and adapted toswing thereon and have notches 16 which receive the cross rod l0 andlock it in the lower end of the guide when the frame is extended. Theplates are connected by a rod 1T and the notches 16 are so arranged thatwhen the plates are swung down to a horizontal position as indicated inF ig. 6, the cross rod will not only be locked firmly but the frame willbe extended so that it will be rigid, and all lost motion in the jointstaken up, and twisting or swaying of the frame when in use prevented. Inother words, the downward swinging of the plates from a vertical to ahorizontal position will exert a cam action on the cross rod l0 andcause it to be forced into the notches in the lower ends of the bars 9and at the same time the final step in the expansion of the frame isperformed. The plates will hang down over the rear axle where the rodconnecting them may be easily struck by the foot of the person pushingthe cartI when it is desired to unlock and collapse the frame.

I-Iandle bars 1S have a common pivot with the upper ends of the bars 8and are pro` vided with extensions 19 projecting beyond said pivots towhich links 20 are pivotally attached connecting the said extensionswith the cross bar l0. Then the handle bars are raised to a verticalposition the links 20 will be swung in toward the bars 9 and the saidbars raised on the rod l0 to expand the frame to its position for using.When the handle bars are pressed downwardly the links 2O will be swungforward and the bars 9 will slide downwardly on the cross bar 10 asindicated in Fig. 2 until they assume a substantially horizontalposition. Brackets 21 are provided on the upper ends of the bars 9 towhich one end of a flexible filling or seat portion 23 for the frame isattached. This fiexible seat is passed under the rod 10 and over the bar7 and secured at its forward end to a foot board 24.- mounted on bars 25that are pivotally supported at their.

rear ends on the bar 7. When the frame is collapsed the seat portionwill be loose as indicated in Figs. 2 and 3, but when the frame isextended this flexible filling will be drawn taut, as shown in Fig. l.

Suitable arms 26 are riveted to the bars S and are adapted to fold downto a horizontal position with these bars when the frame is collapsed.The handle bars, as indicated in Fig. 3, will when the device is folded,be swung in under the frame between the wheels and where they will notin any way interfere with the compact folding or packing of the cart.

I claim as my invention zl.
